Sara Bauder, SDSU Extension Forage Field Specialist, highlights that managing alfalfa during drought conditions requires careful planning and simple management practices. Reducing plant stress and maintaining strong growth are key steps to protect yield and stand life. Farmers focus on soil testing, balanced nutrients, and regular scouting to improve plant health. Monitoring insects and diseases also helps prevent further damage. Limiting field traffic reduces extra stress on the crop.
While rainfall cannot be controlled, farmers can adjust other practices to protect their alfalfa stands. Cutting schedules play an important role during dry conditions. Although producers often aim for higher yield, drought may require fewer and later cuttings to allow plants to recover and maintain strength.
Alfalfa has deep roots, often reaching several feet into the soil. This allows it to find moisture better than many crops. However, it still needs proper care. The plant uses a high amount of water each day, so protecting root reserves is important. When alfalfa reaches full bloom, root energy is restored, which helps the plant survive stress.
During drought, delaying harvest can help improve root strength. While yields may be lower, the feed quality can often be higher. This balance helps farmers manage both crop performance and forage value.
Cutting height is another important factor. Farmers should avoid cutting too close to the ground, as this can damage crown roots. A stubble height of about 2.5 to 4 inches supports healthy regrowth. Leaving too much height may seem helpful, but it can reduce proper growth from crown buds. Maintaining the right balance is important for long-term plant health.
In dry conditions, alfalfa naturally stores energy in its roots and may become dormant to survive. Protecting this process is essential.
Although drought is challenging, following these simple practices helps farmers protect their crops, maintain forage supply, and improve overall outcomes during dry seasons.
